Install Apache, PHP on Centos 8

 

Apache installation on centos 8

To install Apache on CentOS 8, you can use the `dnf` package manager, which is the replacement for `yum` in CentOS 8. Here's a step-by-step guide to installing Apache:

 

1. Open a terminal on your CentOS 8 system.

 

2. Update the package list to ensure you have the latest information about available packages:

sudo dnf update

 

3. Install Apache using the `dnf` package manager:

sudo dnf install httpd

 

4. After the installation is complete, start the Apache service:

sudo systemctl start httpd

 

5. Enable Apache to start on boot:

sudo systemctl enable httpd

 

6. Check the status of Apache to ensure it's running without any issues:

sudo systemctl status httpd

 

7. Adjust the firewall settings to allow incoming HTTP traffic:

sudo firewall-cmd --add-service=http --permanent

sudo firewall-cmd --reload

 

Now, Apache should be installed and running on your CentOS 8 system. You can verify its functionality by opening a web browser and accessing your server's IP address or domain name. You should see the default Apache welcome page if everything is set up correctly.

 

PHP installation on centos 8

 

To install PHP on CentOS 8, you can use the `dnf` package manager. Additionally, you may want to install some commonly used PHP extensions to ensure the proper functioning of PHP-based applications. Here's a step-by-step guide to installing PHP:

 

1. Open a terminal on your CentOS 8 system.

 

2. Update the package list to ensure you have the latest information about available packages:

sudo dnf update

 

3. Install PHP and some commonly used extensions:

sudo dnf install php php-cli php-fpm php-mysqlnd php-pdo php-gd php-xml php-mbstring

 

The packages above include the basic PHP package (`php`), command-line interface (`php-cli`), PHP-FPM (FastCGI Process Manager) for serving PHP through a web server, MySQL support (`php-mysqlnd`), PDO (PHP Data Objects) for database connectivity (`php-pdo`), GD library for image manipulation (`php-gd`), XML support (`php-xml`), and multibyte string support (`php-mbstring`).

 

4. After the installation is complete, start and enable the PHP-FPM service:

sudo systemctl start php-fpm

sudo systemctl enable php-fpm

 

5. Check the status of PHP-FPM to ensure it's running without any issues:

sudo systemctl status php-fpm

 

6. Restart Apache: After making any changes to the Apache or PHP-FPM configuration, restart Apache to apply the changes:

sudo systemctl restart httpd

 

 

Now, PHP is installed and ready to be used on your CentOS 8 system. You can test your PHP installation by creating a PHP file with the following content:

 

<?php

   phpinfo();

?>

 

Save the file as `info.php` in your web server's document root directory (typically `/var/www/html/`):

 

sudo echo "<?php phpinfo(); ?>" > /var/www/html/info.php

 

Then, open a web browser and navigate to `http://your_server_ip/info.php` or `http://your_domain/info.php`. You should see a PHP information page displaying PHP version, configuration settings, and more. Remember to remove this `info.php` file after testing for security reasons.
